If the secondary particles are ions, the effect is termed secondary ion emission.

Another random access computer memory tube based on secondary emission was the Selectron tube.

The number of secondary electrons emitted per incident particle is called secondary emission yield.

In this case, the number of secondary electrons emitted per incident particle is called secondary emission yield.

Another undesirable consequence of secondary emission is that in extreme cases enough charge can flow to the screen grid to overheat and destroy it.
From the en.wikipedia.org
Later tubes had anodes treated to reduce secondary emission, normally an unwanted phenomenon, and were not suitable as dynatron devices.

In some cases, it may lead to secondary emission of visible light upon interaction with matter, as in Cherenkov radiation and radioluminescence.

These electrons are directed by the focusing electrode toward the electron multiplier, where electrons are multiplied by the process of secondary emission.
